I posted this complete paragraph from the RNS earlier in the week - I've split it up below to highlight the points.
Wireline tools included optical televiewer, acoustic televiewer, chargeability, conductivity, density,magnetic susceptibility, full waveform sonic, salinity and temperature. Not all tools were used on all holes surveyed. The data obtained is of good quality and provides detailed geophysical and physical properties of the cover rocks, host sequence and mineralisation.
1. In general, zones of gold and copper mineralisation show a positive magnetic response of significant amplitude
2. Zones of gold and copper mineralisation display a conductivity response of moderate amplitude
3. Zones of increased copper mineralisation show a positive chargeability response
4. Elevated density is co-incident with mineralised zones and there is a large density contract between the cover rocks (Permian) and basement (Proterozoic).
So that reads to me that they can distinguish between the cover rocks and the basement rocks by the elevated density readings and then they can define the mineralised zones with the basement rocks from "3" different types of responses - magnetic, conductivity and chargeability.
As I said in my post before - I think they know (and probably the industry people know) what they have got on their hands - get those drills turning again.
